§102 §103
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . DETAILED ACTION Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1 is/are rejected under 35 U.S.C. 102(a)(1) as being Anticipated by Hackett et al. (US 20040091347 A1). Regarding Claim 1, Hackett discloses: A lift arm assembly (66 & 68) comprising: a frame (30); a base (72), pivotally attached to the frame about a substantially horizontal axis (73) (Fig. 2 & Fig. 7 & Fig. 8); a first actuator (74) directly attached at a first end to the base (102) and at a second end to the frame (100) (Fig. 2 & Fig. 7 & Fig. 8); a loader arm (76) pivotally attached to the base about a substantially horizontal axis (79) (Fig. 2 & Fig. 7 & Fig. 8); and a second actuator (78) attached (116) at a first end to the loader arm (Fig. 2 & Fig. 7 & Fig. 8), configured to pivot the loader arm relative to the base (Fig. 2 & Fig. 7 & Fig. 8) [0046 & 0048]. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 4, 5, 6, 8, 9, 10, 11, and 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hackett et al. (US 20040091347 A1) in view of Sewell (US 20070132204 A1).

Regarding Claim 9, Hackett teaches: a work vehicle (10), comprising: a mainframe (30), configured for operator operation (19) [0038 & 0051 & 0053 & 0060]; the mainframe having a plurality of ground-contacting drive members (172); a base (72), pivotally attached to the mainframe about a first axis (73) (Fig. 2 & Fig. 7 & Fig. 8), wherein the first axis is substantially horizontal (Fig. 2 & Fig. 7 & Fig. 8); and a loader arm (76), pivotally attached to the base about a second axis (79) (Fig. 2 & Fig. 7 & Fig. 8), wherein the second axis is substantially horizontal (Fig. 2 & Fig. 7 & Fig. 8). Hackett does not teach: a mainframe, configured for standing operation; an articulation joint attached to the mainframe; a front assembly (6) pivotally attached to the mainframe by the articulation joint (Fig. 3 & Fig. 8). Sewell teaches: a work vehicle (10), comprising: a mainframe (12), configured for standing operation (22 & 46) [0021 & 0025 & 0028] and having at least one ground-engaging wheel (24); an articulation joint (14 & 32) [0039] attached to the mainframe (Fig. 1 & Fig. 3 & Fig. 4 & Fig. 9 & Fig. 14) [0039]; a front assembly (16 & 64 & 84) pivotally attached to the mainframe by the articulation joint (Fig. 1 & Fig. 3 & Fig. 4 & Fig. 9 & Fig. 14) [0039] and comprising: a frame having a plurality of ground-contacting drive members (40); a base (64), attached to the frame (13) (Fig. 3 & Fig. 8); and a loader arm (84), pivotally attached to the base about a second axis (Fig. 9 & Fig. 14), wherein the second axis is substantially horizontal (Fig. 9 & Fig. 14). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the work vehicle supporting a lift arm assembly taught by Hackett with the articulated work vehicle supporting having a main frame and an articulation joint disposed on the main frame and a front assembly (6) pivotally attached to the mainframe by the articulation joint taught by Sewell in order to provide a work vehicle having a reduced turning radius to increase the versatility of the work vehicle. Regarding Claim 10, Hackett teaches: a first actuator (74) disposed between the frame (100) and the base (102) (Fig. 2 & Fig. 7 & Fig. 8); and a second actuator (78) configured to pivot the loader arm about the second axis (Fig. 2 & Fig. 7 & Fig. 8) [0046 & 0048]. Regarding Claim 11, Hackett teaches: the second actuator is disposed between the base and the loader arm (Fig. 2 & Fig. 7 & Fig. 8). Regarding Claim 12, Hackett teaches: the second axis is disposed closer to the mainframe than the first axis (Fig. 2 & Fig. 7 & Fig. 8). Allowable Subject Matter Claims 2, 3, 7, 13, 14, and 15 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
